B i know that .1, JI N: A- Reea e .e t ni f th Unit Stat s, res ding a Attalla, in the coimty of name and State of Alabama, have invented cert-ainnew and eee e mp ove e ts n Whe l Attac men forMotor "Vehicles, of which the following is a specification.

My invention relates to ai r attacliment for he rear e d ing Wheel o a m t r ve cle and the anai robject of the invention is to provide means for pulling the vehicle out ef rat and mud, r uphil par ieill l on icy roads.

By furnishing vehicle with several of these attachments the driving wheels are practically converted to tractor wheels and it will thus be evident that the vehicle can be propelled over otherwise impassable parts of the road.

In the accompanying drawing one embodiment of the invention is illustrated, and;

Figure l is a fragmentary side elevation of a vehicle wheel with the device attached;

Figure 2 is a section along line 2-2 of Figure 1; and

Figure 3 is a section along line 33 of Figure 1, that is to say, in a circui'nferential plane of the wheel.

In the drawing, reference numeral 10 represents the spokes of an ordinary wheel, 11 the fellv, 12 the rim, and 13 the pneumatic tire. It will be evident, however, that. the device is applicable to wheels with solid tires whether of rubber or metal.

The wheel attachment consists of two shanks 14 adapted to straddle the wheel rim and extend beyond the tread surface of the pneumatic tire 13. The free ends of the shanks 14E are flattened as at 15 presenting broad surfaces in the circumferential direction of the wheel and the edges are preferably beveled as at 22 presenting a sharp edge on the driving side of the wheel. The inner ends of the shanks are joined together by a hinge 16 permitting the spreading out of the shanks to pass outwardly over the pneumatic tire 13.

The shanks 14 are provided with ledges 17 adapted to engage the rim 12 and are for that purpose suitably curved, as best seen in Figure 2. These ledges 17 are preferably wider than the shanks, in order to get a good hold 011 the rim.

011 each shank and near the hinged port n t er of a urnishe arm 1.8, Whieh re e l re et share to eniferm with he nnerpe ip'he y efithe t lly l nd tidal 1e le t th e r whe in peSitea- The l lengt from end t end ef th a m 1 .8 is a li l mer th th d tenee b ween We adjac nt epekies 0 en the Whe and th e d O he arm a e t ee ed a a 9 fi ag hal a e id t ep kei when, in position. This steadies the device notonly in transverse direction, but also in difumf el d lie t ei of the wheel A enemies bel 29 engag s in suitable ert r s 12 in the s ank an is adapted to drew e ett tege l e a d to firefly he h m n ne e t a s e in F gu 2 Whe ssemb ed n t is mann the arms 18 rest'i'ip'on theinner periphery of the fel-ly 11, while the ledges 17 curving partly around the rim 12, draw the shanks outwardly in radial direction, the arms 18 at the same time engaging between two adjacent spokes 10.

WVith several of these attachments secured on the driving wheel, the flat blades 15 at the outer ends of the shanks 17 will take good hold in the ground and raise the vehicle out of a rut, or drive it up a hill without difliculty. On account of the very simple construction of this device, it can i be manufactured at a very small cost. It may be cast or drop-forged and is preferably made of malleable iron.

It is evident that still another use of the device is possible, namely, as a safety device against theft, when the automobile is parked on a hard roadway or street, as it would then be rather difficult to run away with the vehicle with this attachment clamped and locked to the driving wheels.

It is evident that the wheel attachment may be made either as a metal casting or forging as found most suitable.

Having thus described the invention what is claimed as new is:

1. A wheel attachment of the class described comprising a pair of hinged shanks terminating with flattened blades at their free ends, and means for clamping the shanks to the wheel, said means including circumferentially extending arms having abutments adapted to engage with the periphery of the whole felly.

2. A wheel attachment of the class described comprising a pair of hinged shanks engage with the wheel rim, and circumferentially extending arms having abutments adapted to engage With the inner periphery of the wheel telly.

3. A wheel attachment of the class described comprising a pair of hinged shanks terminating with flattened blades at their free ends, means for clamping the shanks to the wheel, said means including opposing gripping ledges on said shanks adapted to engage with the wheel rim, and circumferentially extending arms having abutments adapted to engage With the inner periphery of the wheel telly, said arms having suitable recesses engaging with the spokes of the wheel.

4:. A wheel attachment of the class described comprising a pair of hinged shanks terminating with flattened blades at their free ends, means for clamping the shanks to the wheel, said means including opposing gripping ledges on said shanks adapted to engage with the wheel rim, circumferentially extending arms having abutments adapted to engage With the inner periphery of the wheel felly, said arms having suitable recesses engaging with the spokes of the wheel, and a transversely running clamping bolt through said shanks.

5. A Wheel attachment of the class described comprising a pair of hinged shanks terminating with flattened blades at their free ends, and means for clamping the shanks to the wheel, said means including circumferentially extending arms having abutments adapted to engage with the inner periphery of the wheel telly.

6. A wheel attachment of the class described comprising a pair of hinged shanks terminating with flattened blades at their free ends, and means for clamping the shanks to the wheel, said means including circumferentially extending arms having abutments adapted to engage with the inner periphery of the wheel telly, said arms hav ing suitable recesses engaging with the spokes of the wheel.

In testimony whereofI affix my signature.
